TWlSTlNG-HEAD.

SPECIFICATION forming part of Letters Patent No. 721,527, dated February 24, 1903. 1

Application filed June 20,1902. Serial No. 112,536. (No model.)

T0 on whom it may concern:

Be it known that I, ALBERT TASTE, engineer, a subject of the King of Belgium,residing at Rue David, Verviers, in the Kingdom of Belgium, have invented certain new and useful Improvements Relating'to Spinning or 1 Twisting Frames, of which the following is a arrangement within such tubes of amovable part adapted to obturate the outlet-orifice, and consequently to slightly catch the thread against the wall of this orifice in such a manner as to cause it to rotate with the tube and to become twisted, the pressure exerted upon the thread by this part which the rotation tends to displace and to raise being produced by means of one or several other parts either rigidly connected or not with that serving to I seize the thread.

Three constructional forms of my said device are illustrated in'the accompanying drawings by way of example.

As shown in Figure 1, the torsion-tube a, of cast metal and forming one with the drivingpu11ey,is pierced with a hole of double conicity b and c and contains several balls d, the lowermost of which perfectly obturates the outlet-orifice e. The thread f is slightly pressed by this lower ball against the wall of the orifice a, and is thus caused to rotate with the tube aand to become twisted. Owing to the upper conical portion a, with which the upper ballsrota'te, these latter press upon the lower ball, which the rotation tends to displace and to raise. There follows from this a moderate pressure of the whole upon the nose the part (1, closing the outlet of the tube a, is

rigidly connected by means of a rod 9 with an upper ball, producing the required pressure.

In Fig. 3 the obturating part and the part for producing the pressure are replaced by a single part 72., terminating in an extremity t',

adapted to ob'turate the outlet of the tube.

- I What I claim, and desire to secure by Letters Patent of the United States, is-

1. The combination witha torsion-tube for continuous spinning and twisting'frames having a passage therethrough, said passage having a contracted portion, of means, loosely means independent of the tube arranged within said passage at the place where the double "conicity is present and adapted to exert pressure upon the thread passing through the tube, substantially as described.

3. The combination with a torsion-tube for continuous spinning and twisting frames having a passage extending therethrough, said passage havinga contracted portion, of a ball, fitted into said passagaadapted to block or obstruct the contracted portion thereof.

In testimony whereof I have hereunto set my hand, in presence of two subscribing witnesses, this 4th day of June, 1902.

" TASTE.
